Abstract

This research aims to improve student learning outcomes in Islamic religious education learning by using problem-based learning. This research is a classroom action research that uses four steps, namely planning, action, observation and reflection. The subject of this research is elementary school students. The data of this study was obtained by test and observation techniques. Tests are used to measure learning outcomes and observations are used to analyze the learning activities of teachers and students. The data analysis technique used in this study is descriptive statistics by comparing the results obtained with research success indicators. The results of the study show that problem-based learning can improve student learning outcomes in Islamic religious education learning. This can be seen from the increase in the percentage of student learning completeness in each cycle with details of 40.19% in the pre-cycle, 65.37% in the first cycle and 89.72% in the second cycle. Thus, the use of problem-based learning can be used as an alternative to improve student learning outcomes in Islamic religious education learning.

Abstract

This study aims to determine whether the Community Units (RW) are independently able to handle waste without assistance from the Regional Government. Waste management in Bandung Regency is becoming increasingly complex with the increasingly full capacity of the Sarimukti Final Waste Disposal Site (TPA), West Bandung Regency. This has caused the Regional Government together with the West Java Provincial Government to take strategic steps to reduce the volume of waste sent to the TPA. One of the main strategies that is being actively carried out is to encourage the community to start sorting waste from the source, especially at the household level. In addition, the Bandung Regency Government has also introduced the "Zero Food Waste" program. Data were obtained through surveys, interviews, and direct observations in RW 12, Cimenyan District. The conclusion of this study is that the Community Units (RW) have not been able to manage waste independently without assistance from the Regional Government. The results of the study are expected to help the Regional Government (Pemda) design a more effective waste management strategy

Abstract

Pencapaian pembangunan nasional dapat diraih dari potensi sumber daya manusia yang berkualitas, karena potensi sumber daya manusia ini merupakan modal dasar pembangunan. Dilihat dari transaksi di Indonesia yang semakin luas dan berkembang, perlu adanya pengikat yang sah dari transaksi bisnis tersebut. Perusahaan XYZ merupakan perusahaan yang bergerak di bidang penjualan. Sebagai usaha untuk meningkatkan bisnis tersebut, maka perusahaan perlu mengatur jumlah persediaan produk agar tidak mengalami kekosongan stok dan agar perusahaan tidak mengalami kerugian. Dilihat dari data penjualan produk X pada tahun 2016 sampai dengan tahun 2019, penjualan produk X setiap tahunnya selalu mengalami kenaikan. Maka untuk mengetahui jumlah penjualan pada periode-periode berikutnya akan digunakan metode Double Exponential Smoothing untuk meramalkan jumlah penjualan tersebut. Hasil akhir yang diperoleh yaitu peramalan berupa nilai jumlah penjualan produk X pada perusahaan XYZ pada periode-periode berikutnya, dimana semakin banyak periode yang diramalkan maka akan semakin tinggi pula hasil peramalan jumlah produk X yang terjual.   Forecasting Analysis of Product X Sales at Company XYZ Using Double Exponential Smoothing Method Achievement of national development can be achieved from the potential of quality human resources, because the potential of these human resources is the basic capital of development. Judging from the transaction in Indonesia, which is getting wider and growing, it is necessary to have a legal binding of the business transaction. XYZ Company is a company engaged in sales. In an effort to improve the business, the company needs to regulate the amount of product inventory so that it does not experience a stock vacancy and so that the company does not experience losses. Judging from the sales data for product X from 2016 to 2019, sales of product X always increase every year. So to find out the number of sales in the following periods, the Double Exponential Smoothing method will be used to predict the number of sales. The final result obtained is forecasting in the form of the value of the number of sales of product X at company XYZ in the following periods, where the more periods are forecasted, the higher the forecasting results for the number of products X sold.

Abstract

Pada masa kini perkembangan teknologi telah memacu meningkatnya kepemilikan kendaraan, terutama di beberapa kota seperti Jakarta, Bandung, Yogyakarta, dan kota besar lainnya. Situasi ini menimbulkan masalah yaitu kemacetan lalu lintas dimana salah satu penyebabnya adalah kepemilikan kendaraan yang semakin bertambah setiap tahun. Kondisi ini tidak didukung dengan keadaan infrastruktur dan sumber daya yang terbatas, disamping fasilitas lalu lintas yang pengoperasiannya masih belum optimal. Penyebab lain dari kemacetan lalu lintas ini adalah banyaknya angkutan umum yang sering berhenti sembarangan, keluar masuk area parkir, dan persilangan kendaraan di persimpangan. Oleh karena itu pada artikel ini dilakukan penelitian untuk mengetahui penyebab dalam masalah kemacetan dan diharapkan ditemukan solusi pemecahan masalah. Dalam penelitian ini, dirancang sistem simulasi arus lalu lintas dengan menggunakan aplikasi SimEvents yang dijalankan pada software MATLAB Simulink. Berdasarkan simulasi, dapat diprediksi penyebab kemacetan lalu lintas khususnya di lokasi Bundaran Balubur Town Square (BALTOS) Kota Bandung Jawa Barat.Kata kunci : kemacetan, lalu lintas, simevents, matlab

Abstract

Technology is present and becomes a part of human life. Each era has its own technological advantages. The history of technology begins millions of years ago. The first technology discovered by mankind was to create sharp stone chips which were used as stones. Then humans began to develop and found several technologies, one of which was computers and the internet. computers and the internet have a close relationship, especially in today's era where all activities cannot be separated from computers and the internet. One of these activities is in the office world. The Bandung City Health Office is a government agency that has a lot of data, especially in the section where the author is placed, namely the Division of Human Resources and Health or SDMK. The SDMK Division is tasked with receiving data on the credit score of a functional position from the assessment team to calculate whether a functional position is eligible for promotion or not. On that basis, the purpose of this paper is to create an application for inputting the credit score for a functional position based on a web database to make it easier for the assessment team, SDMK to view, recap and change credit scores as well as a functional position in viewing its credit score. The main finding is a web database-based application called E-PAK.

Abstract

Mathematics is the basic foundation for other sciences. Equation is a mathematical model that can describe real-life problems, one of which is estimating non-tax state revenues in the coming year. Non-State Revenue (penerimaan negara bukan pajak, PNBP) is the scope of state finances which is equipped with the State Assets and Auction Service Office (kantor pelayanan keuangan negara dan lelang, KPKNL) which must be reported on the realization of PNBP that will be deposited into the state treasury. Such situation happens because expenditures in each government agency will be available and increase every year by the government. Therefore, direktorat jenderal keuangan negara (DJKN) have to be more optimal in the management of the PNBP. This study aims to determine the results of the best estimates and exponential models in estimating non-tax state income at the KPKNL Bandung, Indonesia, in year of 2017 and 2018. This research includes descriptive research using a qualitative approach. The results show that the calculation using the exponential 4th model is the best model for estimating PNBP such that the estimated PNBP results in 2017 is Rp. 574,775,677 and in 2018 is Rp. 798,022,691.
